The KP reform debate is the recurring policy controversy within the Kimberley Process Certification Scheme over whether the definition of conflict diamond should be widened beyond its narrow 2003 wording. The current KP definition restricts the term to rough diamonds used by rebel movements or their allies to finance conflict aimed at undermining legitimate governments. Civil society organisations and a growing number of governments have argued for two decades that this language excludes most of the human rights abuses the public understands a conflict diamond to involve.

Origins of the narrow definition

The 2003 definition reflects the political compromises required to launch the scheme in the first place. The original NGO campaign of the late 1990s focused specifically on rebel movements, particularly UNITA in Angola, the RUF in Sierra Leone and rebel groups in the Democratic Republic of the Congo, that had used rough diamond sales to finance civil wars against internationally recognised governments. The scheme was conceived as a remedy for that specific harm, and the definition was drafted accordingly.

Criticisms of the definition

The narrow scope leaves several categories of harm outside the regulatory reach of the KP. Diamonds extracted under conditions of state-sponsored violence against artisanal miners, as documented at Marange in Zimbabwe between 2008 and 2011, are not conflict diamonds within the meaning of the scheme. Goods linked to forced labour, child labour, or the displacement of communities by mining concessions fall outside its remit. Stones smuggled from countries under United Nations sanctions but routed through compliant participants enter the legitimate trade once they are in possession of a KP certificate.

Civil society members of the KP Civil Society Coalition, led for many years by Global Witness, IMPACT (formerly Partnership Africa Canada) and successor organisations, have argued that all of these scenarios should be brought within the conflict diamond definition. They propose language tied to systematic violence and human rights abuses against any party, regardless of whether the perpetrator is a rebel group, government security force, private security contractor, or corporate actor.

Industry and governmental positions

The major industry observer body, the World Diamond Council, has voiced support for an expanded definition in principle and has updated its own System of Warranties to cover human rights and labour standards alongside the original conflict-financing language. Producer governments are split. African producers including Botswana, Namibia and South Africa have generally supported gradual reform under their own terms; some have resisted reforms perceived as expanding northern oversight of African mining policy. Russia and Zimbabwe have historically opposed expansion. Western consuming-country governments, including Canada, the United States and most European Union members, have supported reform with varying degrees of energy.

Procedural state of the debate

The KP operates by consensus. Any single Participant can block a definitional amendment, which means twenty years of discussion have produced policy statements and supplementary measures rather than a redrafted definition. The Ad Hoc Committee on Review and Reform, established to consider definitional and structural reforms, has issued multiple reports without producing a consensus text. Civil society members have periodically withdrawn or boycotted plenary sessions in protest. The 2018 introductory chair's statement under the European Union presidency, the 2022 Russian-Ukrainian crisis, and various ongoing disputes have all complicated the consensus environment.

Implications for the trade

For working jewellers and dealers, the practical consequence of the unresolved debate is that a Kimberley Process certificate alone is no longer sufficient evidence of responsible sourcing in the broader sense customers now use the term. Compliance jewellers supplement KP documentation with OECD Due Diligence Guidance for Responsible Supply Chains of Minerals, Responsible Jewellery Council certification, country-of-origin attestations, and increasingly with provenance technologies (laser inscription, blockchain ledgers, isotopic and trace-element fingerprinting). The reform debate is therefore not academic: it shapes the structure of supplier audits, the language of customer-facing claims, and the legal exposure of dealers who rely on a single certificate as evidence of due diligence.

Outlook

Substantive amendment of the conflict diamond definition continues to be improbable on the consensus timetable. More likely paths are the strengthening of supplementary measures (peer review, statistics, due-diligence guidance) and the migration of the responsible sourcing conversation to industry-led regimes that operate alongside but outside the KP. Trade members should expect to maintain parallel documentation systems for the foreseeable future.
